Finite element analysis on buckling behaviour of integrated wing spar
2024
Overview
With advancement in manufacturing processes like 3D printing, it is easy to manufacture the components. This study focuses on the numerical simulation of an aircraft wing and spar as an integral component. The study examines the buckling behaviour of the integrated wing spar, a critical load carrying member in the wing. The spar is connected to the wing so that the buckling analysis can be performed on the wing as well. CATIA software is used to design the integrated wing spar model as well as the conventional wing spar model, and ANSYS software is used to perform FEA analysis for both the wing spars. Under different loading circumstances, the structural performance of both the wing spars is compared. Buckling occurs in both the spars. But the stress acting on the conventional spar is 280MPa whereas, the stress acting the integrated wing spar is 348MPa which is comparatively higher by 13.5%. Based on the buckling stress, strain, weight savings and cost, the results reveal that the integrated wing spar design is better than the conventional wing spar design.
